MACHINE FOR THE PRODUCTION OF TEXTILE FABRICS.

Application filed May 8, 1926, Serial No. 107,659, and in Switzerland May 21,1925.

invention relates to'certain new and useful improvements in machines for producing fabrics of different'kind, light fabrics such as tulle, bobbin net, fancy net, woven lace, braids fancy gauze.

The mainobject of the present invention is to provide'a machine for the production of suchtextile fabrics, which is simple in construction and which may be readily adapted to any work.

Other jects of the invention'relate to the g and?) show end-elevations of the machine. Figs. 6, 7, 8, 9, 10,11 partly in'section.

The machine illustrated is'provided with two side frames 1, 2 in which a driving shaft and 12 show details 3 is rotatably mounted. The shaft 3, through the medium ofchain gear 4, 5 drives a shaft 6 to which is keyed part'of a worm wheel thread 7. The latter engages upon rotation of shaft 6 a worm wheel 8 which is keyed to a shaft 9' at right angles tothe shafts 3. On the rotation of the shaft 3 and 6 an intermittent motion'is given to wheel 8 and there with to shaft 9. On the shaft Qaremount ed two discs 10, 11' (Fig. in which are provided radial rowsof holes 12. In the holes 12 are interchangeably 'mounted rollers 13. The discs 10, 11 actuate by means oftheir rollers 13 two horizontally disposed bars 14,15 which are slidably mounted in the machine frame '1, 2 independently of each other. The bars'lt, 15 are at the same level parallel one to the other; each is provided with an arm 16, projecting upwardly into the path of the rollers 13 and ,each is under the action ofa spring 17 which tends to draw the corresponding bar 14, 15 toward the right Fig. 2, so that they bear against the any time. The bars 14, 15 are provided with slots 17 at right angles tothe longitudinal direction, which end'towardsthe edges of the bar-s14, 15, which are turned towards one another. In these slots 17 are mounted bobbin carriers 18 (Figs. 7 and 8)' so as to be readily movable. Each bobbin carrier carries ayarn bobbin 19 (Fig. 8). Further, there is provided for each bobbin carrier 18'or'fo-r eacli slot 17 an actuating rod 20, which is movably' mounted on the machine frame. The rods 20 are arranged in two rows to both sidesof the bars 14, 15, a rod being always movably mounted adjacent each slot 1 7 in the direction of: these slots 17; I For each row of-rods 20 there are providedpusher cylinders 22, These pusher cylinders 22, 23 are hollow and are provided with grooves 25in the longitudinaldirection, for example eight grooves in which arelitted bars or pasteboard cards, 24 which are perforated in a similar manner as in'jacquard apparatus according to a predete-ri'nined pattern of the fabric to be manufactured. The cylinders 22, 23 are'rot'atably and slidably mounted in horizontal slots of the machine frame 1, 2

by means of pivots 4, 5 they run parallel to those rods of a row are moved inwardly I which cannot pass into'a hole in the jacquard card 24; The perforating of the jacquard card 24is effected as in jacquard apparatus,

motion about their own axes and for moving.

the cylinders 22, 23in a horizontal direction'there are rotatably mountedon the two sides of the machine frame 1, 2 two shafts 27,28 which are driven from the main driving shaft 3 by means of toothed wheels 30-and an intermediateshaft 81. The shaft Sis providedwith two bevel gears SSdriving onsaid intermediate shafts 31. On each of the shafts 27-, 28' there are keyed two drums 40, 41 with-cam grooves cut into their circumference: Driving pins 42 which are rigidly connected to links 44 mesh with said grooves. These links 44 are pivotallycon-, nected tothe pivot pins 45 of the pushing cylinders 22, 2- The shape of the grooves in the drums 40, 41 is such that at each complete revolution 01 one of the shafts 27, 28 the pushing cylinders 22, 23 are moved fully inwards towards the corresponding bar 14 or 15 and again returned to the initial position. For this purpose the grooves of the two drums 40, 41 are'so arranged with reference to each other that while one pushing cylinder is moved inwardly the other pushing cylinder is moved simultaneously outwardly.

The'two pushing cylinders '22, 23 might also be simultaneously moved inwards and again return simultaneously by forming the grooves in the drums 40, 41 accordingly. ()nly in this case the bobbin carriers 19 must be arranged in alternate slots 17 of the bars 14, 15 that an occupied slot 17 of one bar will always be opposite an empty slot 17 of the other bar 14, or 15 in each working position. half of all the slots 17 are litted with bobbin carriers 19. To the pivots 45 of the pushing cylinders 22, 23 there is also connected a bar 47 (Figs. 3 and 11) by means of links 44 (Fig. 11). The rods 20 are provided with collars 46 with which the bars 47 engage. The bars 47 are reciprocated together with the pushing cylinders 22, 23, and they bring the rods 20 back to their initial position. To rotate the pushing cylinders 22, 2 there is secured to one pivot 45 of each cylinder 22, 23, a worm wheel 48. A. driving element 49 forming part of aworm thread and rigidly mounted on the shaft 31 engages said wheel 48 once each rotation of shaft 31. The rotation ol' the pivot 45 and therewith the rotation of the pushing cylinders 22, 23 is always eifected when the cylinders 22, 23 have reached their outermost position or when they are not in ei'igagement with the rods. Above the bars 14, 15 there is mounted in the frame 1, 2 a roller 51 for the reception of the fabric produced. This roller is advanced by a known apparatus, not illustrat ed and described in detail, as the reduction of the fabric proceeds. Undernea h the bars 14, 15 there are also provided warp beams 52 from which the warp is guided vertically upwards by known guide means between the bars 14, 15.

In order to produce "fabric, the bobbin carriers 18 are pushed from the bar 14 into the other bar 15 and vice versa, and this moven'i'ent of the bobbin carrierslS is effect-- ed according to the perforations of the jacquard cards 24 which are secured to the cylinders 22, 23. By this movement of the bobbin carriers 18 from one bar 14 to the other bar 15 and by the simultaneous movement of the bars 14, 15 parallel one to the other the threads from the separate bobbins 19 are Consequently as a maximum only caused to be looped. The bars 14, 15 according to the adjustment of the rollers 13 can be relatively displaced by one or more slots 17.

In order to produce a twist connection or a thread looping, as is the case when weavin" tulle, a bobbin carrier 18 is fitted as follows: {Vhere there is a bobbin carrier 18 in a slot 17 ot a bar, the opposite slot 17 in the other bar is empty. Then all the bobbin carriers 18 are moved from one bar 14 into the other 15 or vice versa. Hereupon the bobbin carriers 18 are again moved into the other bar 14 or 15. Operating further in this manner two bobbin carriers 18 would always follow one another in a circle and the two threads would be twisted. By IDOV'. ing the bars 14, 15 laterally through diilerentdistances and by alternately moving the bobbin carriers 18 it is possible that the same two threads will not always-be twisted together but that always a dillerent adjacent thread is twisted in and finally all the threads have'becn inter-looped, as in a net. i What 1 wish to secure by'U. S. Letters Patent is:

1.. Machine forthe production of textile fabrics, comprising in combination, a fabric beam, an automatic take-up motion, two bars relatively adjustable, yarn carriers, guides on said bars for said carriers, means to adjust the two bars relatively, said means comprising for each bar a disc, advanced-in steps, having adjustable driving members, which can move the bar to a predetermined extent, and active to resist such movement, means for moving the yarn carriers from one bar to the other for the purpose of looping the threads leading from the yarn carriers to the fabric beam selectively together and-if desired with warp and warp threads.

2. ll'lachine for the production of textile fabrics, comprising, in combination, a tabric beam, an automatic take-up motion, two bars relatively adjustable, yarn carriers, guides on said bars for said carriers, means to adjust the two bars relatively, said means comprising for each bar a disc advanced in.
